The RobotKeySanityTest is tricky, it requires the user to press a lot of keys to get good coverage but can produce confusing results if the user presses certain keys, like AltGr. Windows treats AltGr as if you pressed Ctrl and Alt at the same time. This means the OS sends two events when you press the key and two more when you release it. This is confusing the RobotKeySanityTest which can only handle one press/release pair at a time. I'm not sure I can fix the test but will think about it.

The KeyboardTest app that I recently added to PR #425 covers most of the same ground and avoids the problematic keys. The downside of KeyboardTest is that it only provides good coverage for specific layouts (I'll try to add Spanish) and provides the best coverage when run against multiple layouts which takes effort to set up.

I've written an app that just logs key events as the user types and that would probably be a better candidate to attach to some PR. When something confusing happens with RobotKeySanityTest or KeyboardTest that's the app I pull up to diagnose what's going on (like I just did with AltGr).
